12S Mapping question

As Roger said, an EFI module is the way to go.
In addition, as he says, a dyno would help you dial it in completely but I have to say, IMO, and for my usage, a dyno final tune was unnecessary. I simply adjusted the Techlusion module to their optional settings for a bike with a full exhaust system and modified air filter. The bike runs great and at least 90% of the exhaust popping/backfire is gone.
If you can read and push a button, you can do it.

I took by our local indep. BMW guy today and he plugged into the ECU and did some checks. He said both lambda sensors were right on and within range and that I'm not running lean.

Again, as I said, they're relatively narrow band devices, and are obviously not getting the transition. The System IS lean, and can ONLY be lean, as you're config'd. It's not like most dealers understand motor control systems (though some of course do, and very well - but it's the exception)

I am sure it is within the suggested range for optimal exhaust emissions, which is what the specs are written to. If you want optimum power, you will need some help. The BMW tech is just gonna tell you the bike is in spec.

[Rick Lee]

This wasn't a dealer tech. This is the independent BMW guru everyone goes to around here and I think he's as competent and honest as the day is long. He usually tries to talk me out of spending money and often doesn't let me pay him when I think I've used up a lot of his shop time. I'm sure the Phoenix folks here know who I'm talking about. Anyway, I am still interested in getting whatever performance I can out of this bike, expecially since I won't have to get it through emissions again before 2012. I just would like to do all my research and take my time. BTW, this guy has a full machine shop and is building me a set of bar risers. So I will report back how that works.

[roger albert]

So a non dealer tech has the full new bmw computer?
And he has it somehow reading a pair of wideband lambda sensors?
None of that makes any technical sense (that I can fathom anyway)

[Rick Lee]

I don't know what he was using. He had a GS-911 when he worked on my GS and access to some dealer stuff once in a while. All I know is he plugged into my interface and it brought up a lot of info on the bike, hours, miles, temps, etc. He showed me the graphs for each sensor and said they were fine.

Now I just read a lot on the FRK vs. Techlusion and am really confused. I'm not looking to throw money away, but if I can take some horsies back off the table for under $300, I'll do it. It just comes out of my ammo stockpile budget.

Appears that their side requires some re-making. PC guys here they say that PC V is available ...but only for 08/09 models (which is weird because there's no 09 model and 06-08 are rather unchanged - if we forget that clear coat thing).

Contact any PC dealer to clarify. All what matters is the auto-tune capability. I've done this with this ultra expensive RB3 gizmo (a tuner has it here in Greece) and results are rather impressive...anyway within RB3 capabilities.

Given the price difference (and the open PC mentality - maps et all)...I can't imagine a reason why someone should opt for RapidBike.

[roger albert]

gs911 just reads narrow band.
doubt your mech is ignorant enough to believe the bike is really rich, but who knows.
In any event, it's the wrong tool, and the wrong conclusion.

[Rick Lee]

Where did I say he said it was rich? He said it was not too lean.

No body is trying to twist your arm or anything but the earlier posts were about the popping and backfiring. I think we've established that while incomplete combustion causing a portion of the fuel charge to enter the exhaust system still burning can be caused by either a less than ideal rich or lean condition but your modifications lend itself toward a lean-ing condition, not so much that it's way too lean but that it is on the lean side of things, ergo, your noisy exhaust on de-accel, smells, etc.
If your technician is looking for a gross "problem", he may not find one. Perhaps that's where the mixed message is-you have a lean type condition that can be dramatically improved with an adjustable EFI module like a Techlusion FI-1334ST. I'm sure your bike is ruunning pretty good as was mine before I installed the module. It's just running noticably better now. If you explain it to your tech that way rather than searching for a "problem" which he is not finding, the 2 positions/explanations start to align.

Whew! I can't explain any clearer than that-you'll have to do what you are going to do. I can only tell you that you are $249 and some button pushing away from a better running R12S.

Regarding installing a Techlusion;

That sums it up pretty good............It took me a little longer to install mine as I am a picky bastard.........and finally found a nice safe spot for the module under the rear seat section.

But once installed.........it is just a matter of pushing a few buttons to try new settings.

A dyno with a sniffer would be nice for set up........but I think you will be amazed as to how easy this is to make the bike run better.

Mine idles better........has a nice linear power curve and no flat spot like it did in stock trim.

Hope this helps.
Cheers

Prob didn't. That was apparently an inadvertent amalgam of your input (smells rich) and your 3rd person account of the tech's opinion (not too lean)

Didn't mean to ruffle.

Folks, that have a vague idea of how to read a motor's symptoms, are just trying to help you here. We don't mean to cause no trouble.

Roger, I think Mr. Lee's tech was looking for a "problem" vs. trying to improve a lean condition which as you point out, most bikes have these days. Mr. Lee's got to do what Mr. Lee will do-he's got all the info.

[Rick Lee]

Ok, I'm getting one of these units. I just want to read up some more on reviews of the FRK.

Good move there, Leester.

I've been in the motor vehicle/powersports business for 30 years and talked to a lot of people who "know" what they are doing.
Roger knows what he's doing.
When you figure out how that FRK module works, let me know, will you?

I'm not looking for a problem, in that I'm a hypochondriac. I just want to know if I have symptoms of a dangerously lean condition. Since I've only had the bike for 2000 miles and it had 7500 miles on it before I got it, I'm kind of curious if damage has been done. I've had serious issues in Porsche engines before due to incorrect mixtures and it doesn't take long for those issues to become very expensive. So, while I do want to get something like a Techlusion to smooth things out a bit, I'm more concerned with whether I'm gonna find some burnt up valves next time I pull the covers off to adjust them.

That's a reasonable concern.
I don't believe your bike is "dangerously lean" but, based on your description, I'm sure you can be more satisfied with it's performance with a little bit of cash-ish.
Good luck to you.

[shreddr]

If hes getting 60 mpg there is reason to believe it is dangerously lean, especially with the add-ons he has. And you wont find the burnt up valves when you pull the covers, you will have to pull the heads to see that, but if you are concerned you can pull the intake or exhaust and have a peak.

If he's getting 60 mpg consistently, I've got a bridge in Brooklyn that's available. Maybe's he's interested. How could it be that lean just putting a full Remus system on the bike?
